SAFETY DEVICE FOR PI STOLS.

T al lfwhom it may concern 1..

Be'it known that I, UNO STONE, a citizen of the United States, residing at Lead city,

Pistols; and do hereby declarethe following tobe' a full, clear, and exact description of the invention, such as will enable others skille'din the art to which it appertains to make and use the same.

My invention relates to a safety device for pistols or other fire arms, and the object of my invention is to provide such a device whichcan be easily locked and unlocked at will, so that when the said safety device is locked the pistol or other fire arm cannot be firedat all. Tofthese ends my invention consists in the novel Combination of parts hereinafter more fully disclosed, and particularly pointed out in the claims.

,Be'ferrin'g to the accompanying drawings forming a part of this specification, and in which like letters'refer to like parts in all the views Figure 1 represents a side elevation of a pisto with my invention applied thereto; Fig. 2 a sectional view taken through the grip of the pistol and showing the barrel portionbroken away; Fig. 3, a rear elevational view of a pistol provided with my device, with the safety lever removed, and my improvement in its closed position; Fig. 4, a ike elevational view of the pistol grip with the lever removed, and my safety device in an open osition; Fig. 5, a cross sectional view of t 1e safety lever, and of my safety locking device taken on the line 5-5 of Fig. 3,:showing my safety device in .its closed osition; Fig. 6, a like view, taken on the mes 66 Fig. 4, with my safety device in its open osition; and Fig. 7, a perspective detachec view of my improved safety lock.

- In the above drawings A represents the trigger of any suitable fire arm, in this case shown as a self-acting revolver, B represents the sear, C the hammer, .D a locking lever pivoted at D, and normally pressed down by the spring E and thereby preventing the hammer from being cocked.

F represents a safety lever adapted to control the locking lever D by means of a projection G contacting with the notch H in said locking lever D. This safety lever F is Specification of Letters Patent.

pivoted at F to the frame of the revolver, and is provided with a slot 1, a small distance above said pivot. Over this slot fits the thumb button J secured by a screw K to the projection M of my locking device L, which issecured'to the frame of the revolver by a screw N, as shown. This safety lever looking device L is provided with threeopenings O, P and Q, as best shown in Fig. 7, and also with two spring tongues R rovidjed with flanges S. Through the mid 1e opening P, the screw N passes: when the tongues R are closed, and the opening Q receives said screw N when the said tongues, R are in their 0 en position. The flanges S are separated w ien the tongues R are opened, and pass under the sides T of the safety lever F, as best shown in Fig. 6, and thereby lock.th e same against movement. The said tongues R are separated by pressing on the thumb button J and sliding the same over the slotI downward toward the end of the pistol grip.

\Nhen the said safety device L is thus moved longitudinally, the projections V, which separate the openings Q and P, take against said screw N and causethe separation of the said tongues R, as best shown in Fig. 4.

The operation of my device is as follows 1* VVhen the pistolis to be fired, the thumb button J. isp'ushed to its uppermost position, shown in Fig. l,'the handle of the'pistol gripped, tile trigger pulled, when the'pressure of the hand on the safety lever F will cause the hammer to be unlocked, then the pistol may be fired in the usual and well-known manner. When it is desired, however, to prevent the locking lever D from being moved out of its locking position, from behind the hammer C. When in this position,

it is impossible for the hammer to move forward and explode the cartridge, no matter how hard the trigger may be pulled, nor how hard the safety lever F may be pressed. By this means-I not only provide a revolver or other fire arm, which is normally safe except when gripped for firing, but I also provide a described.

sald hammer, a safety lever 1 provided with means for locking the normal safety means, and thereby prevent any firing at all when the said normal safety means are locked.

Having now described my invention, what I claim, is

1. In a the arm, the combination of a tri ger, a hammer, a locking lever normally loc ring said hammer, a safety lever normally adapted to move said locking lever from its locking position behind the hammer, means to lock said safety lever, and sliding means to remove said last-mentioned locking means out of their locking position, substantially as 2. In a tire arm, the combination of a trigger, a scar, a hammer, a locking lever D adapted to normally loclr said hammer, a spring E adapted to normally force said lockmg lever D into its locking position behind an extension G, adapted to normally contact with said locking lever D, and provided with a slotI, a button J sliding over said slot, and means connected with said button adapted to lock said safety lever F, substantially as described.

3. In a self-acting revolver, the oombinw tion of a trigger A, a sear B, a hammer (J, a locking lever D, a safety lever F, provided with an extension G adapted to contact with said locking lever I), and provided with a slot I near its lower end, a locking device L provided with an extension M extending through said slot 1, and a thumb button J for operatin said extension M, substantially as described.

4. In a self-acting revolver, the combination of the trigger A, a scar B, a hammer (l, a locking lever I), a safety lever .1 provided with a slot 1, a locking device L provided with the spring jaws lt, means on said jaws adapted to lock said safety lever I when the said jaws are spread apart, and a thumb button J extending over said slot I adapted to 1 operate said locking device l1, substantially as described.

5. in a self-acting revolver, the combination of the trigger A, the sear B, the hannner C, the locking lever .iivoted at D, the spring 1:] adapted to hold said locking lever in its looking jmsition, and said locking lever provided with the notch ll the safety lever F, provided with the extension (l, adapted to enter said notch H, and also provided with the slot 1, the locking device L provided with the openings 1 and Q, the spring jaws R, the flanges S, the extension M. passing through said slot 1, the thumb button J secured to said extension M, and tl srrew N, substantiall, as described.

6. in tire arms, the combination with the safety lever thereof, of a locking device {or said'satety levers, con'lprising the spring jaws lt, the flanges S, the holes P and Q, and the extension M, substantially as described.

7. In lire arms, the 'coml'iination of the safety lever F and a locking device L provided with two spring controlled devices adapted to spread apart and underlie the edges of said safety lever and means for separating said devices at will, substantially as IlOSGIlbGd.

8. 1n lire arms, the combinat ion of a safety lever, and a locking device for said lever, comprising spring jaws it and llanges S adapted to lock said lever, substantially as described.

9.- ln lire arms, the combination of a safety lever F and a locking device provided with the holes 1 and Q, the spring jaws R, the flanges S, and the extension M, substantially as described.

In testimony whereof, .I aflix my signature, in presence of two witnesses.
